Mixing Tranexamic Acid into Lotion/Cream based on Water Content

Based on the staff's reply, whether you can mix tranexamic acid directly into your lotion or cream depends on the water content of the product.

• If the lotion/cream contains enough water, you can add tranexamic acid directly as it will dissolve in the existing water.
• If the lotion/cream contains no water or very little water, you will need to dissolve the tranexamic acid in water first before adding it to the product.

To check if your lotion/cream contains water, look at the ingredient list on the label. Determining the exact amount of water requires experience in reading labels. You can also try mixing a small amount of your lotion/cream with tranexamic acid separately to see if it dissolves properly.
